Functions
These functions add/subtract at a constant rate.
Linear functions
A pair of numbers that describes the location of a point on a graph.
Coordinate
Write and label the Simple Formula for Linear Functions.
y = mx + b
The angle of the steepness of a line.
Slope
The shape made by graphing a Quadratic function.
Parabola
These functions multiply at a constant rate.
Exponential functions
The point where the function begins or touches the y-axis.
Y-intercept
Write and label the Simple Formula for Exponential Functions
The minimum or maximum point of a parabola.
The highest point of a parabola when it is concave down.
Maximum (vertex)
Any function that grows by the power of two! The growth of these functions adds by two each time.
Quadratic Functions
The point(s) where two or more lines cross. This point is also the solution to each line it touches.
Intersection
Any coordinate that satisfies an equation or sits on the line of that equation
Solution
The growth of a linear function.
Slope
The main study of Algebra:
Things that take an input, apply a rule, and produce an output.
Functions
These functions model things like population growth, depreciation, and compound interest investments.
Exponential functions
The annotation we use to show the slope of a function on a graph.
Slope Triangle
Write and Label the Simple Formula for Quadratic Functions
y = x2
DAILY DOUBLE
The middle point of a parabola where the curve turns around.
Vertex
The central intersection of the axes on a graph.
Origin
These functions model things like the path of a basketball shot or homerun hit, a satellite dish, and the Golden Gate Bridge.
Quadratic functions
DAILY DOUBLE
The root of a function, or where it touches the x-axis.
X-intercept or Zero
The name for a group of equations with the same variables.
System of Equations
When a parabola opens upward like a smile it is called...
Concave Up
When something is made up of exactly mirrored parts on either side of an imaginary line or axis, it is...
Symmetrical
Write a real-life example of each of the three function families.
Linear:
Exponential:
Quadratic:
Draw an example of the three common types of Linear slope:
Positive:
Zero:
Negative:
Replace an unknown variable with a known value.
Substitute
3x + 21 = 11x + 5
The value of x that solves this equation is...
x = 2
x = 4
Write a different equation where x = 4.
10x = 40
3x – 2 = 10
x + 1 = 5
